USA vs Kenya

Hey guys. I am in a difficult position. I got invited for a job in the USA, earning 20 dollars an hour. I have googled around and don't think it's a good idea leaving my job, at Safaricom, earning 60k a month for that. I understand the quality of living is better there, but foregoing a comfortable life here to go live minimalistic doesn't sound right. Please advise, from your experiences. Thanks
